HCC-20S vertical rotary fan flow Qs refers to standard suction state (absolute pressure 101.325kPa, temperature 20 ℃, relative humidity of 50%) Zhangqiu rotary fan, the medium is the air inlet flow rotary blowers Shandong rotary fan, for non-standard state flow segment for conversion. HCC-20S vertical rotary fan flow conversion: When the intake air flow rate with the reference state (temperature 0 ℃, absolute pressure 101.325kPa) volume Qn is represented, you must first press converted to the volume Qs standard intake state post , and then check the performance table (usually not considered humidity). Qs = 1.0733Qn ts when the intake air temperature and 20 ℃ difference between the larger, or inhalation of the gas molecular weight M deviate significantly from the molecular weight of air 29, the actual intake air flow rate Qs calculated: Qb = (Qth-Qsa) × [(273 + ts) / (273 + 20) × 29 / M] 1/2 where: Qb- suction gas temperature ts ℃, the molecular weight of internal leakage when M m3 / min; Qth- theoretical flow m3 / min; ( According to the requirements of the boost declining chip fan inlet flow, according to the performance table after the initial selection by the performance table Richard). Actual m3 Qsa- standard suction state / min flow rate. (Flow performance shown in the table after the initial selection) listed performance parameters with air as the medium, such as the transmission media or other intake state with the standard input does not match a state where good air rotary fan, flow need to be converted accordingly. Operating principle Rotary blower fan is biased against the inner cylinder rotor eccentric operation, and volume change blade rotor slots between the air intake, compression, spit. The blower pressure difference in the operation automatic lubrication to drip nozzle inner cylinder was dropped to reduce friction and noise rotary fan, while maintaining the cylinder of gas is not reflux. Rotary fan their maintenance knowledge 1, must be hand use, personal service. 2, allowed sick to run. 3, periodically clear the dust inside, especially on the impeller dust, dirt and other impurities, in order to prevent corrosion and imbalances. 4, repairs must be emphasized first stop off. 5, a thermometer and regularly check the sensitivity of the subject of oil.
